Pruning raspberry bushes is an important part of ensuring a bountiful harvest, as well as keeping the plants healthy and attractive. The good news is that pruning raspberries is relatively easy, and even new gardeners can quickly learn how to do it.

Before you start pruning, it’s important to understand what type of raspberry bush you have. There are two main types of raspberries: summer-bearing and everbearing. Summer-bearing raspberries produce fruit on canes (or stems) that grew the previous year Everbearing raspberries produce fruit on canes that grew the same year.

Once you know what type of bush you have, you can begin pruning.

Why You Should Prune Raspberries

Raspberries are a summertime favorite for many people. They are delicious and can be used in a variety of recipes. Raspberries can be grown in most areas of the country and are relatively easy to take care of. In order to get the most out of your raspberry plants, it is important to prune them properly.

To encourage fruit production

Raspberries are a fruiting shrub that produce fruits on 2-year-old canes. Because of this, improper pruning can drastically reduce yields. Each spring, you should remove all of the canes that fruited the previous year. These canes will be gray or brown in color and will have cracked, flaking bark near the base of the plant. Additionally, any weak or spindly canes should be removed to make room for strong, healthy growth.

To improve air circulation

Pruning raspberries allows for better air circulation, which helps to prevent mold and mildew from forming on the plants. Air circulation also helps to keep the leaves dry, which reduces the likelihood of fungal diseases.

To prevent the spread of disease

Raspberries are susceptible to a number of diseases, including root rot, anthracnose, cane blight, and fruit rot. Pruning helps to prevent the spread of disease by removing infected canes and allowing for better airflow throughout the plant.

In addition, pruning raspberries helps to encourage new growth, which is important for producing high-quality fruit. New canes are typically more disease-resistant than older ones, so pruning helps to ensure that your plants are bearing the best fruit possible.

When to Prune Raspberries

Pruning raspberries is an important part of their care. Raspberries should be pruned in late winter or early spring, before new growth begins. This will help ensure that the plant produces healthy, strong canes that are able to support the fruit. It will also help promote good air circulation, which will reduce the chances of disease.

In late winter or early spring

Pruning raspberries is an important part of their care. It not only helps to keep the plants tidy, but also stimulates new growth and encourages fruit production.

Raspberries should be pruned in late winter or early spring, before new growth begins. Begin by removing any dead or diseased canes, as well as any canes that are thin or weak. thinning the canes helps to improve air circulation and prevent problems with pests and diseases.

Next, cut the remaining canes down to about 6-8 inches tall. This will encourage new growth that will produce fruit for the upcoming season. After pruning, be sure to mulch around the plants to help protect them from winter weather and keep the roots cool in summer.

After the harvest

After the harvest, cut all of the fruiting canes that bore fruit back to the ground. This will encourage the plant to put its energy into new growth that will fruit next year. New canes will grow from the base of the plant and should be left to grow unchecked until mid-summer. At that point, you can select the strongest looking 8-10 canes and remove all of the others. These selected canes should be spaced about 8 inches apart.

How to Prune Raspberries

It’s easy to learn how to prune raspberries for optimal growth. You should start pruning when the plant is young, and continue to prune every year. By pruning, you will encourage the plant to produce more fruit, and the fruit will be larger and tastier.

Cut out dead or diseased canes

If you have dead or diseased canes, cut them out at the base and throw them away. Diseased canes will be thin, with small leaves, and may be discolored. If you’re not sure if a cane is dead, scrape away the bark with your thumbnail. If the wood beneath is green, the cane is alive; if it’s brown, it’s dead.

Cut out weak or spindly canes

In late winter or early spring, before new growth begins, cut out any weak or spindly canes (canes thinner than a pencil) that grew the previous season. Also remove any canes that are more than 2 years old, as they tend to produce fewer and poorer quality berries.

After you’ve removed the weak and old canes, cut the remaining canes to about 4 feet (1.2 m) tall. This will encourage the plant to produce new, strong canes that will yield a good crop of delicious berries!

Cut out canes that are crossing or rubbing

Cut out any raspberry canes that are crossing or rubbing against other canes. Canes that are rubbing can damage each other, and the damage provides an entry point for diseases.

In general, you should remove about one-third of the canes each year. This thinning allows air and sunlight to reach the center of the plant, promoting strong growth. It also helps prevent overcrowding, which can lead to poor fruit production.


In conclusion, pruning raspberries is an essential part of optimally growing them. By removing old canes, diseased or dying canes, and suckers, you will promote air circulation and encourage new growth. This will result in a healthier plant that is better able to produce delicious fruit.
